To all whom zf may concern:

Be it known that I, Gorrrnmn Bnons, citizen of the German State,residing at No, 16 Aschafl'enburgerstrasse, Berlin, W. 30, Germany, haveinvented a certain new and useful Anchor, of which the following is aspecification.

The present invention relates to a so called folding or patent anchorand its principal distinguishing feature is that the two flukes togetherare heavier than the re mainder of the lower portion of the anchor, sothat the dukes of the anchor according to this invention gripimmediately they touch the ground owing to the position oi their centreof gravity and furthermore that the fiukes immediately penetrate furtherinto the ground at the spot where the anchor is dropped.

In folding anchors as hitherto constructed and consisting of a stem andtwo arms which are provided with flukes and are pivoted to the stem androtate conjointly through an angle of about 90, the centre of gravity ofthe whole arrangement lies in the vicinity of the centre of the pivotbolt. This type of anchor has also a base plate which lies in the centreof the arms of the fiukes and is rigidly connected thereto. The lowerpart ofthis plate, which, in the idle position in which the tlukes liein a plane with the stem, is situated at right angles to this latter.serves, after the anchor has been dropped and after tension has acted onthe stem of the anchor, to efiect a rotary movement in a directionopposite to that in which the anchor is pulled, and thereby to turn thefiukes downwards into the ground.

As, however, in these known anchors, the weight of the flukes isextraordinarily small in comparison with the weight of the arms of theanchor, the plate, the pivot member and the lower end of the stem, theseanchors do not, in most cases, grip bottom at once, butare frequentlydragged for considerable distances before doing so. In ground which isunsuitable for anchoring, for instance, ground which is covered withweeds or ooze, these anchors either do not grip bottom at all or do soonly in an unreliable manner.

In a bed of weeds, for example, an anchor of the kind hitherto knownsinks with its heavier part gradually deeper and deeper, while thecomparatively light flukes tend to revolve with the arms about the pivotand Application filed July 24, 1922. Serial No. 5716395 1to pointupwards and consequently do not ig pi All these disadvantages areobviated by the anchor according to the present inven 'tion and in asatisfactory manner. The inrportant feature of the anchor according tothe present invention is that both flukes to gether are heavier than theremainder of the lower portion of the anchor. Accordingly the lower partat least of the stem the arms of the anchor and the pivot member aremade of comparatively light weight,

shaping them suitably, while yet retaining perfect stability, so that,for example, when such an anchor is sunk into weed covered ground, thepoints of the fiukes. in contradistinction to the known anchors, firstpenetrate and then on sinking in deeper grip efiectively owing to thearms and stem of the anchor lagging behind. The like resuit is obtainedwhen the anchor sinks into other kinds of ground, such as that which isoozy or composed of sand.

I When the anchor according to this invenon is suspended from the chain,it sets itself in such a position, by reason of the particulardistribution or? the weight, that the stem does not lie in line with thechain but obliquely thereto and consequently the points of the flukesare from the outset located considerably nearer to the horizontal planewhile the anchor is being lowered into the water than is the case withthe anchors hitherto known the stem or which hangs practically verticalin line with the chain.

In the case of very small anchors which can be thrown by hand, thetechnical advantage of the anchor according to this invention is thatthese anchors, when suilicient chain is paid out, will settle in thewater with their fiukes pointing downwards with the result that theygrip bottom whichever way they turn. This is important because thedrifting of small boats, as well as large ships, from the place where itis intended to anchor involves great danger of stranding and damageowing to the proximity of the unnavigable waters or the coast.

The anchor according to this invention grips bottom at once at the placewhere it touches the ground and on further traction being exerted on itburies itself to its maxi mum depth in the ground at this point so thatthe safety of both ship and crew are thereby very considerablyaugmented.
